qemu-img currently writes disk images using writeback and filling up the cache buffers which are then flushed by the kernel preventing other processes from accessing the storage. This is particularly bad in cluster environments where time-based algorithms might be in place and accessing the storage within certain timeouts is critical. This patch adds the option to choose a cache method when writing disk images. Signed-off-by: Federico Simoncelli <fsimonce@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
